So when playing with a PKA-S after longer not using zoomed sights, I noticed that my aim is thrown off completly.
I tried to set up the settings in a way that the sensitivity wouldnt change when aiming, for consistency and muscle memory.
It works somewhat, but any sight with zoom has reduced sensitivity when scoped in.
I noticed that sniper scopes reduced that sensitivity to a third.
So my suggestion is to add a setting that allows to turn off that sensitivity change because some people just prefer it and good players in any fps game tend to suggest using such a setting and Godstatus also has his sensitivity set up in a similar way.
It could also be a slider that lets you change how much the multiplier changes sensitivity.
